Original No. 1,531,082, dated Hatch 24, 1925 Serial No. 749,174, led November 11, y1924. Application for reissue led July 10, 1925.

To all whom it may 4concern:

it known that CHARLES H. DoUGLAss, vcitizen ofA the United States, formerly residing at Cranston, in the county of Providence and Stateof certain new land useful Improvements in Self-Threading Shuttles, for which v Letters Patent No. 1,531,082 were ranted under date of March 24, 1925, and `tat Anna- C. Douglass, executrix of Charles H. Douglass, now makes applica.- tion for reissue of said Letters Patent, of which the following is a specification.

The invention relates to self-threading shuttles and particularly to the delivery end thereof including the threading block therein located.

Heretofore the delivery yendl of shuttle frames or bodies at a point above and in the rear of the delivery eye have presented a joint occasioned by a laterally projecting metal lip or the like upon the metal threading block seated inthe wood of the Ebody. This joint has invited wear, accidental engagement of the filling, "and abrasion or splitting of the wood adjacent the li during the reciprocation of the shuttle. his has also increased the 'expense of construction of the shuttle at the point indicated.

The essential lobjects of the invention are to overcome the above disadvantages, and to increase the of the shuttle; to facilitate the admission of the filling; and to insure a position of the threading block remote from the lateral portions of the nose or delivery end of the sh i To the above ends essentially the invention consists in such parts and in such combinations of parts as fall within the Scope ed claims. c the accompanying drawings which form a part of this specilication` Fi 1 is a plan View of a shuttle embodying` t e invention;

In the construction of the shuttle herein represents the frame or body portion provided .with the usual bobbin chamber 16 for `a bobbin 17. The delivery end or nose portion` of the shuttle is indlc-ated by 18. Axially of the of reference indicate like 23,1a stud 24 thereon d in an opening 25, parallel or spaced vertical side walls or webs 26 and 27 boundlng a longitudinal thread passage 28. A portion 29 of the cavity 20'extends beyond the end of the block and constitutes a part of the passage 28. The block 22 is fixed in place by the usual transversely disposed screw 30 traversing openings 31 andk32 in the block and in the undercut beak 38 whose body portion 39 is longitudinally disposed and whose point 40 is inwardly directed. The lateral enlar ement ofthe beak fits in a'cavity 41. ntegral with the top of the wall 27 is a longitudinally disposed forwardly directed finger is sufficiently vspaced from the overlapping portion 44 to admit the introduction of a filling thread into the passage 28.v

transversely disposed rearwardly inclined curvilinear thread passage 47 extends from' the longitudinal passage to the lateral face ofthe nose and' communicates at its lower portion with the delivery eye 48. One wall of the passage 47-is formed by the convex face of an inwardly directed beak 50 which extends from one side of the nose 18 to the frontv of the beak point.40, so that v the wooden beak -50 embraces theside and forward end portion of the metallic beak. The filling thread passes from the bobbin through the passages and the delivery eye in the usual manner. l f

It will be observed that the presence of `the beak 50 reduces the. width of the delivery end of the shuttle at the. point` 51 where the cheek of the shuttle is usually so excessively prominent as to mosts readily interfere with the shuttle box; that no lateral lugs are by the portion 39, hence there is labsent any joint` ofmetal'or` wood near the side of the shuttle to occasion exposure to violent Contactv withthe shuttle box; that the nward position of the wooden beak as well as its support and ro-tection of the metal beak end 40 strengtiiens the structure; and that the beak 50 increases the guiding area of the filler.

What is claimed is:

1. Al shuttle comprising a. body and a de- 1 livery` end, a vguide block disposed centrally Y of the delivery endl comprising parallel side wallsfbounding alongitudinal thread passage,ja lon itudinally disposed forwardly projecting nger von one wall, a longitudinally disposed beak on the second wall terminating adjacent the projecting portion of this constructiony required ont the finger, the delivery end being provided with a laterally disposed thread passage communicating withA the longitudinal thread passage, and an auxiliary beak extending from the, side ofthe delivery end toy the forward portion of the first beak.

2. A self-threading shuttle for looms having a'longitudinally extending thread passage and side delivery eye,I aI metallic beak having its end directed towards the longitudinally extending thread passage, and a portion of the metallic beak and forming al jointless guide passage for the thread to the vside delivery eye.

3. A self-threading shuttle 'for looms having a longitudinally extending thread passage and side delivery eye, a' metallic beak having its end directed towardsthe longi-` tudinally extending thread wooden beak formedjby'the wood of the shuttle to'co-ver the side and'forward portion of the metallic beak and providing a jointless guide passage for the thread to the side delivery eye.

In testimony whereof, I have affixed my signature to this specification.'
